Mozilla has made Firefox Hello, its WebRTC-based communication feature as a system addon. This change should come to the stable channel of Firefox with version 45. If you have no use for Firefox Hello, you might want to disable it. However, it is not clear or obvious how to do that so let me show you.
On Windows, system add-ons are located in the folder C:\Program Files\Mozilla Firefox\browser\features. On 64-bit Windows, 32-bit Firefox add-ons will be installed to the folder C:\Program Files (x86)\Mozilla Firefox\browser\features.
Note: If you installed your Firefox browser in some custom folder, you need to correct the "C:\Program Files\Mozilla Firefox" part.
Firefox Hello already became a system add-on in Firefox Nightly. It will be included in the Stable release branch with Firefox 45.
To disable and uninstall Firefox Hello add-on, do the following:
- Close Firefox.
- Go to browser\features subfolder (e.g. C:\Program Files\Mozilla Firefox\browser\features) and delete the firstname.lastname@example.org file.
This will remove the Firefox Hello add-on and the appropriate feature from Firefox. The Hello icon on the address bar will disappear as well.
Keep in mind that every time you upgrade Firefox, the Hello add-on will be re-installed. Unless Mozilla removes it from the Firefox default bundle, there is no way to avoid this. So, every time you upgrade Firefox, you need to repeat these steps.
